This book illustrates the principle of NODAL analysis using bottom-hole as the solution node where IPR is readily available for predicting the productivities of wells with simple trajectories. For more complicated well trajectories, such as multilateral wells, an iteration procedure proposed by Guo et al. (2006) can predict well productivity. It uses a trial-and-error method to couple pressures, flow rates, and fluid properties in different wellbore branches, and equipment such as down-hole chokes to estimate oil and gas production at the surface.
72 air = 1 estimate density and viscosity of the crude oil at 50°C: at 15 MPa and at 20 MPa. 43 44 2-8 2-9 Chapter 2 For the gas composition given below, determine the apparent molecular weight, specific gravity, pseudocritical pressure, and pseudocritical temperature of the gas. 75 specific gravity gas at 85°C: at 1 MPa, 5 MPa, 10 MPa, and at 50 MPa. 73 specific gravity gas at 80°C: at 1 MPa, 5 MPa, 10 MPa, and at 50 MPa. Compare the results with those given by the Brill and Beggs’ correlation.
The tubing string is in tension all the way down to the packer. The “Christmas Tree” is connected to the tubing head by an adaptor and regulates fluid flow from the well (Figure 1–8). The Christmas Tree may have one flow outlet (a tee) or two flow outlets (a cross). A typical Christmas Tree consists of a master valve, wing valves, and a needle valve, located just below the tubing pressure gauge. The master valve and wing valves can close the well partially or completely when needed, but to replace the master valve itself, the tubing must be plugged.
